Is it just me or is anyone else perturbed that the cable sizes in this infographic are all the same gauge?

They’re not. They are clearly marked as different gauges, except the left most two which have different plug types… one is two prong, the other is three prong.

Do you just mean the art showing them as the same size? Because that’s common in a lot of infovraphics to not be to scale if they are clearly labeled

a 50ft 12 gauge extension cord is about $40
$40USD would be $58CAD.
A 50-ft 12-gauge extension cord costs $112+ CAD anywhere in Canada. A 100-ft is $200+ CAD. Like… fffffuuuuuck.

Space heaters are “medium duty” while a router is “heavy duty”?

Oohkay.

It’s for putting holes in things. Creating routes? I dunno.

router as in ‘tool for finer details in woodworking.’ most router motors can spin at 10000rpm at their lowest and anything with a motor, by definition, uses more power than something without a motor

It doesn’t make sense. Temperature difference does not depends on length.
lightnsfw@reddthat.com 3 months ago
Adding length creates more resistance which creates more heat. Thinner conductors can’t handle it as well.
uis@lemm.ee 3 months ago
And more surface area for heat dissipation. lemm.ee/comment/17115060

TIL. Maybe I was conflating daisy-chaining power strips with extension cords and came up with that as a reason it was bad.

lol “gauge”
americans will use anything except the metric system
Successful_Try543@feddit.org 3 months ago
16 AWG – 1.3 mm^2
14 AWG – 2 mm^2 12 AWG – 3.3 mm^2 10 AWG – 5 mm^2
For us from the civilised part of the world ;-)
However, as in Europe we have 230 V system, approximately half the cross section, stated in the table above, is sufficient.

Both are measurements of cross-sectional AREA and are defined in terms of square millimeters (mm^2), not mm.
Successful_Try543@feddit.org 3 months ago
That’s exactly what I wrote
mm^2should be rendered to square millimetres (mm^2) by the browser / appThavron@lemmy.ca 3 months ago
I’ve always found gauge to be especially odd, because the number gets smaller as you go bigger, so at one point you can’t go any further even though you can go fatter.
spizzat2@lemm.ee 3 months ago
Oh, you can get bigger! Just keep adding 0s. It’s fine.

Yup, I work with 4/0 (0000) cable pretty regularly, for things like generators or powering large systems. We have a few trunks full of cable, and it takes a crew of 2 or 3 to actually lay it because it’s so heavy. Usually one person pushing the trunk along, one focuses on uncoiling it from the trunk, and one focuses on actually laying the cable. We use five conductors at a time (one neutral, three 120v hots leads, and a ground,) so it’s a big bundle. Each cable weighs a little over a pound per foot, and there are five bundled together. So a 150’ coil can easily weigh 750-800 pounds.

Oh ffs I should’ve known.

What is the metric unit for cables?
lime@feddit.nu 3 months ago
for cross-sectional area? mm^2^.
